This cover is secured tened. The pump is now operated to force roo in place by rods 7 and 8, the former of which water from the tank 4 up through the pipe 5o passes through an apertured lug 9 on the 14, through the pump, through the pipe 16 cover, through apertnred lugs 10 in the cylinto the cylinder under the piston, and thus inder, and is provided at its upper end with elevates said piston. In its upward movement the piston forces the material supported thereby out through the nozzle 2l in the usual manner.

In large cities and towns Where there is sufficient Water-pressure the pump may be dispensed with and the water-service pipe connected directly to the lower end of the cylinder and the piston elevated, as above described. In that event a draw-off cock is also located in the cylinder at its lower end to permit the Water to be drained from the cylinder and allow the piston 5 to lower therein.

As shown in Fig. l of the drawings, after the piston has been elevated and it be desired to recharge the cylinder the valve 18 is opened,

thus allowing the Water from the cylinder l to reenter the tank 4.

As shown in Fig. 2, in which the invention is adapted for use as a lard-press, I have removed the cover and placed in the open end of the cylinder a perforated shell which is of slightly less diameter than the inner diameter of the cylinder and rests with its open end on the piston or plunger. A clearer-head 22 projects into the cylinder and is provided with astem 23, which is secured to a crosshead 24, supported by rods 25, secured to the lugs l0 of thecylinder.

In operation, assuming the piston to be at its lowermost point within the cylinder and the perforated shell seated thereupon, the cracklngs are placed inside the perforated cylinder and the head 22 adjusted and firmly held Within the perforated shell or cylinder. Water under pressure is applied to the cylinder under the piston and forces the piston, with shell and the cracklings therein contained, upwardly, and thus causes the lard to flow out through the perforations in the shell into the space between the shell and cylinder and thence out through the nozzle 2l in the manner previously described in connection Vwith the sausage-stufling machine.

It will thus be seen that the invention has a double use in that it may be used as asausage-stuffing machine and also by the addition of a few simple parts may be converted into a lard-press.

From the foregoing description, taken in connection with the accompanying drawings, the construction, mode of operation, and ad- Vantages of my invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and details of construction may be made within the scope of the invention without departing from the spirit or sacrificing any of the advantages thereof.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

l. In a device of the character described, the combination With a cylinder having an outlet at its upper end and an inlet at its lower end, of a piston located Within said cylinder, a perforated shell supported by said piston and of less diameter than the interior diameter of the cylinder, and a clearer-head supported Within said shell, and, as the piston moves upwardly with the shell, adapted to force t-he material supported by said piston through the perforations in the shell, substantially as set forth.

2. In a device of the character described, the combination of a cylinder provided at its lower end with a water-inlet and atits uppel` end with fastening devices, a piston located within said cylinder, a perforated shell supported by said piston and adapted to slide therewith Within the cylinder, a clearer-head arranged Within the shell, and a frame secured to the top of the cylinder by said fastening devices and supporting the clearerhead, substantially in the manner set forth. In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
